A STUDY OF CORRELATIONS AMONG TERRESTRIAL TEMPERATITRES. 365 



SO far south as Galveston. The further examination of this point must be left to 

 meteorologists. 



§ 14. Tnhidar Exhibit of Ten-day Departures During the Period 1872 to 1904. 



Tlie original departures are shown in the following tables in the form which 

 seemed best adapted to facilitate a critical examination and working out of the results. 

 The means are the unweighted ones of the several regions, and are therefore the values 

 of T to be used in the formulfe of § 4. 



The regions are : Eastern United States, Western United States, Argentina 

 and Apia. 



At the bottom of each annual column is given the algebraic sum of the departures, 

 wliich will be useful in any test to which the work may be submitted. By dividing 

 these terms by 36 we have annual deviations for the different regions, which should 

 not differ much from those used in chapter III. 



The comparison of the sum of the means with the mean of the sums may be used 

 to test the accuracy of the computation. 



Below each sum is given the sum of the squares of the 36 departures. These are 

 used in the formulse of § 4.
